Recursive Agent Optimization (RAO) presents a novel reinforcement learning framework designed specifically to train agents capable of recursive self-delegation and task division. This approach offers significant advantages in training efficiency, enabling models to handle contexts exceeding standard window limits while solving more complex problems than single-agent systems. By optimizing how agents spawn sub-instances to communicate and delegate work, RAO effectively addresses scalability challenges inherent in current inference architectures.

Recursive Agent Optimization

arXiv2 min read

arXiv:2605.06639v2 Announce Type: replace-cross Abstract: We introduce Recursive Agent Optimization (RAO), a reinforcement learning approach for training recursive agents: agents that can spawn and delegate sub-tasks to new instantiations of themselves recursively. Recursive agents implement an inference-time scaling algorithm that naturally allows agents to scale to longer contexts and generalize to more difficult problems via divide-and-conquer. RAO provides a method to train models to best take advantage of such recursive inference, teaching agents when and how to delegate and communicate. We find that recursive agents trained in this way enjoy better training efficiency, can scale to tasks that go beyond the model's context window, generalize to tasks much harder than the ones the agent was trained on, and can enjoy reduced wall-clock time compared to single-agent systems.
